A lunar lander is descending toward the moon's surface. Until the lander reaches the surface, its height above the surface of the moon is given by y\left( t \right) = b - ct + dt^2, where b = 740 m is the initial height of the lander …

Darwin proposed that the Moon formed far closer to Earth than it is now. Let’s see just how close it could possibly be to Earth and survive. In particular, in the next 4 problems you will find the distance from Earth at which the …
